What Is Whirlybird Roof Ventilation?
Whirlybirds are a roof ventilation system that allows air to move hot air out of the ceiling and roof cavities. Sometimes called turbine vents, Whirlybirds are dome-shaped cylinders that are installed on the top of roofs. While they are usually driven by wind (passive), there are some Whirlybird roof ventilation systems that are electrically powered (active). Passive Whirlybirds are the most popular as they are inexpensive to run while still providing effective ventilation.
When the harsh Brisbane sun starts heating up your roof and ceiling, the Whirlybird extracts the heat and circulates it up and out. This helps prevent the interior of the house from heating up further. Whirlybirds also allow any trapped moisture from humidity or condensation to escape the roof cavity which staves off the development of mould in your home. The amount of air flow produced by your Whirlybird will depend on:
- Size of the opening
- Size of the whirlybird
- Make and model
- Wind speed
Passive Whirlybirds usually require a wind speed of about 8kph to work effectively. If you live in an area that rarely gets any wind, for example if you are surrounded by trees or in a valley, you may want to consider an active, electrically-powered Whirlybird. Otherwise, you could also opt for a larger Whirlybird which creates a larger airflow.
